Retirement tax questions

Thank you.  I know that I don't have the qualifying income, but CA's system wouldn't allow me to input "0" as a value.  Once I left it blank, the form was submitted.  Now I just have to wait 21 days to see if they agree.  I don't mind California but this is one of the few reasons, I want to have nothing to do with the state.  They commonly go after non-resident military members for money.  We have to prove that we are not residents and don't have any qualifying income that they can tax.  Last time, while on deployment, they put a $900 lean against my bank account because they claimed I owed them that amount in taxes.
